Subject: [PATCH net-next] net: mana: Add gdma stats to ethtool output for mana
Extended performance counter stats in 'ethtool -S <interface>'
for MANA VF to include GDMA tx LSO packets and bytes count.
Tested-on: Ubuntu22
Testcases:
1. LISA testcase:
PERF-NETWORK-TCP-THROUGHPUT-MULTICONNECTION-NTTTCP-Synthetic
2. LISA testcase:
PERF-NETWORK-TCP-THROUGHPUT-MULTICONNECTION-NTTTCP-SRIOV
3. Validated the GDMA stat packets and byte counters
Signed-off-by: Shradha Gupta <shradhagupta@...ux.microsoft.com>
